mql4 is not respecting validation and EXECUTION when opening the candle.
O[shift ] = iOpen(symboll, timeFrame, shift);
On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

No MT4: A menos que o gráfico atual seja aquele(s) símbolo(s)/TF(s) específico(s) referenciado(s), você deve lidar com erros 4066/4073 antes de acessar os valores da vela/indicador. Histórico de downloads no MQL4 EA - Fórum de programação MQL4 - Página 3 #26.4 (20 19 )
Mt4 is full of defects...
Mt5 the prices don't match, you can get an mt4 and another mt5 account from the same broker, the values don't match...
We are lost, it seems purposeful to lose our money...
I'm trying to understand what you sent me, I'm learning English and using Google Translate, thank you for trying to help me.

I'm learning, I hope it's what you explained in the link you sent, I'm learning to program, learning English, and trying to be a trader, it's not easy hahaha.

I tried to use this before doing the analyzes I need, but the platform is working, here's what I tried to do to get the correct data:
void ValidatePattern(string symboll, int timeFrame) { // Switch to the desired chart ChartSetSymbolPeriod(0, symboll, timeFrame); Sleep(1000); // Wait a while to ensure the graph is updated // Converting the time frame number to a readable string string timeFrameName; switch (timeFrame) { case 1: timeFrameName = "M1"; break; case 5: timeFrameName = "M5"; break; case 15: timeFrameName = "M15"; break; case 30: timeFrameName = "M30"; break; case 60: timeFrameName = "H1"; break; case 240: timeFrameName = "H4"; break; case 1440: timeFrameName = "D1"; break; case 10080:timeFrameName = "W1"; break; case 43200:timeFrameName = "MN"; break; default: timeFrameName = "Unknown"; break; } // Try to load candle data for (int shift = 1; shift <= 3; shift++) { if (!LoadHistoricalData(symboll, timeFrame, shift)) { Print("Error loading historical data for ", symboll, " in timeframe ", timeFrame); return; // If the data cannot be loaded, exit the function } O[shift] = iOpen(symboll, timeFrame, shift); H[shift] = iHigh(symboll, timeFrame, shift); L[shift] = iLow(symboll, timeFrame, shift); C[shift] = iClose(symboll, timeFrame, shift); T[shift] = iTime(symboll, timeFrame, shift); // Store candle opening time }

I added the .mql4 code so that I could run it and check for errors when filling in the data for the O[0] candlestick. The first time it runs, it passes all the pairs correctly, but then the errors start, and it doesn't work in the strategy tester.
Thank you for your attention Roeder .
ChartSetSymbolPeriod(0, symboll, timeFrame); Sleep(1000); // Wait a while to ensure the graph is updated
Perhaps you should read the manual. That does nothing until you return.

Moved to MT4.
I have a comparison specify (O[1] < C[1]) and I want that when opening the zero candle it makes the comparison and giving ok in the same opening, in the same candle that confirmed the desired pattern it executes the alert and the order , however, he is waiting for the ZERO candle that confirmed the pattern (O[1] < C[1]) to close and only after the opening of a new candle will he issue the alert and execute the order. I need help.
